본 연구는 간호대학생의 MBTI 선호유형에 따라 스트레스, 수면의 질, 사회적 지지가 스트레스에 미치는 영향을 파악하기 위해 시행되었다. 간호대학생 290명을 대상으로 하여 구조화된 설문지를 배부하였으며, SPSS 18.0 프로그램을 이용하여 서술적 통계, t-test, 상관분석, 다중회귀분석을 시행하였다. MBTI의 선호유형에 따라 스트레스에 영향을 미치는 요인을 살펴본 결과, 외향형일수록 수면의 질이 스트레스에 영향을 미치고(${\beta}=.23$, t= 2.01, p=.047), 사고형일수록 물질적지지(${\beta}=.06$, t=.77, p=.025), 판단형일수록 평가적지지(${\beta}=.24$, t=1.52, p=.014), 인식형일수록 자존감지지(${\beta}=-.21$, t=-.35, p=.011)가 스트레스에 더 많이 영향을 미치는 것으로 나타났다. 따라서, 간호대학생의 스트레스 관리 시 MBTI 선호유형에 따른 개별적 중재방안이 필요하며, 학과, 대학 및 전문가의 융합을 통해 체계적인 프로그램 개발이 요구된다.

2016~2017년 '국가해양생태계 종합조사(연안생태계)'에서 얻어진 495개의 퇴적물 중금속 자료를 이용하여 한반도 연안 퇴적물의 중금속 배경농도를 산정하고 오염도를 평가하였다. 퇴적물 입도를 나타내는 지시자로 Al, Cs, Li이 적절하였으며, 이 들과 중금속 농도 사이의 관계에서 이상치 제거 및 잔차 분석을 통하여 가장 낮은 기울기의 자료를 선택하여 중금속과 지시자 사이의 회귀 직선으로 배경농도를 표시하였다. 기존 연구에서의 배경농도와 본 연구의 결과는 비교적 잘 일치하였으며, 본 연구에서는 As 및 Cd에 대해 처음으로 제시하였고, 지시자로 Li을 사용한 배경농도 식을 처음으로 제시하였다.

The speed of sound (SOS) value is an indicator of bone mineral density (BMD). Previous genome-wide association (GWA) studies have identified a number of genes, whose variations may affect BMD levels. However, their biological implications have been elusive. We re-analyzed the GWA study dataset for the SOS values in skeletal sites of 4,659 Korean women, using a gene-set analysis software, GSA-SNP. We identified 10 common representative GO terms, and 17 candidate genes between these two traits (PGS < 0.05). Implication of these GO terms and genes in the bone mechanism is well supported by the literature survey. Interestingly, the significance levels of some member genes were inversely related, in several gene-sets that were shared between two skeletal sites. This implies that biological process, rather than SNP or gene, is the substantial unit of genetic association for SOS in bone. In conclusion, our findings may provide new insights into the biological mechanisms for BMD.

The purpose of this study is to investigate distribution of the vegetation and insects of coastal dunes in the Yangyang area. The field survey was carried out Osan and Dongho coastal dunes during the period from June to July 2008. A total of 68 taxa were identified including 30 families, 60 genera, 59 species, and 9 varieties. 1 species(Glehnia littoralis) was recorded as designated rare plant of Korea Forest Service. The naturalized plants were 8 families, 13 species. The urbanization rate of naturalization index was 4.8% and 19.1% respectively. The land insect appeared with the 10 order, 23 families including 10 Korean specific species and 16 environmental indicator species for coastal dune. The species in Order Coleoptera was most, followed by Hemiptera, Orthoptera and Odonata respectively.

Data mining is the method to find useful information for large amounts of data in database. It is used to find hidden knowledge by massive data, unexpectedly pattern, relation to new rule. The methods of data mining are association rules, decision tree, clustering, neural network and so on. Association rule mining searches for interesting relationships among items in a given large data set. Association rules are frequently used by retail stores to assist in marketing, advertising, floor placement, and inventory control. There are three primary quality measures for association rule, support and confidence and lift. We analyze Gyeongnam social indicator survey data using association rule technique for environmental information discovery. We can use to environmental preservation and environmental improvement by association rule outputs.

This study suggests 5 evaluation criteria (safety and technology, environmental impact, economic feasibility, social factors, and institutional factors) and 24 evaluation indicators for a NFC (nuclear fuel cycle) derived using factor analysis. To do so, a survey using 1 on 1 interview was given to nuclear energy experts and local residents who live near nuclear power plants. In addition, by conducting a factor analysis, homogeneous evaluation indicators were grouped with the same evaluation criteria, and unnecessary evaluation criteria and evaluation indicators were dropped out. As a result of analyzing the weight of evaluation criteria with the sample of nuclear power experts and the general public, both sides recognized safety as the most important evaluation criterion, and the social factors such as public acceptance appeared to be ranked as more important evaluation criteria by the nuclear energy experts than the general public.

During the period of 1975-76, a survey was carried out to find out zinc indicators in the natural vegetation in Korea. The symptoms fo chlorosis were observed in flowering plants in the areas of zinc outcrop of Wolgok-A, Seokgok-9, and Sowolgok. Although 28 species were found to be chlorotic, the total quantity of chlorotic foliage observed was small. Reasons for chlorosis in the areas of zinc are deposits is considered as effects of zinc, lead, copper and calcium ions. Sedum sp. and Dianthus sinensis were confined to soil containing more than exchangeable zinc of 30 ppm and to accumulation in the plants contained at least 1,300-14,000 ppm of zinc. Therefore Sedum sp. and Dianthus sinensis might be used as zinc indicators in Korea.

Nutrient (i.e., nitrogen and phosphorus) budgets are required under a 'Livestock Excreta Survey'. A nutrient budget is one of the agri-environmental indicators that calculates the difference between the inputs and outputs of the amount of nutrients within a certain boundary and for a certain time period (e.g., 1 year). In this study, a nutrients budget model was developed to effectively determine the surplus of nutrients within a region in Korea. The C# program language was used in order to facilitate the deployment of a graphical user interface (GUI) and to enhance compatibility. Also, the model was developed on Windows OS, which is the commonly used operating system in Korea. The model was based on the OECD/Eurostat nutrient budget method, and it was modified to consider manure composting procedures as well. There are key features of the nutrient budget model, including directly use of the original data sets from various input and output sources, and a collectively exchange of the address in different formats. The model can quickly show the results of various spatial and temporal resolutions with the same data, as well as perform a sensitivity analysis with coefficients and easily compareresults using tables and graphs. Further, it would be necessary to study the extension of the scope of utilization, such as the application of various nutrient budget methods. It would also be helpful to investigate both pre and postprocessing information such as linking input data through online systems.
